Sept. 20, 1932. w. A. ADAMS DISPLAY DEVICE Filed Aug. 13, 1931 INVENTOR-Edam ATTORNEY- Patented Sept. 20, 1932 UNITED STATES 7 WILLIAM A. ADAMS,F BROOKLYN, NEW YORK A DIsrLAYjDnvroE a Application filed August13,,ie1. Serial $56,782:

the shade, it is intended by me that, due to a certain angularconfiguration of said shade, the effect to the observer will be that thefish are rising and falling in their travel movements and also that theoutlines of their forms vary in an'amusing manner.

Similar effects are obtainable when the objects pictorially representedon the transparency are hounds chasing a quarry, huntsmen, ocean waves,or other objects capable of motion.

In obtaining this new motion effect for a projected pictorialrepresentation I employ a shade that is composed of a suitabletranslucent material, such for example as ground or frosted glass,making said shade polyg onal in cross-section, with its sidesconcavoconvex, and having its points of intersection rounded or blunt,said shade having in crosssection or plan view generally the appearanceof a star whose points are rounded off.

As the transparent cylinder, which may be of cellophane or othersuitable-material, rotates Within this angled shade, the figuresprojected from the cylinder on the interior of said shade appear to theobserver to be enlarged as they pass the rounded points of intersection,and attenuated as they pass the concavo-convex sides, thereby alsoproviding the further effect of rising and falling as these figures passin review.

Other features and advantages of my invention will hereinafter appear.

In the drawing:

Figure 1 is a side sectional elevation of a device embodying thefeatures of my invention.

Fig. 2 is a horizontal section thereof, taken on the line 22 ofFig. 1.

Fig. 4 is an enlarged view of the trans- Fig. .3 is a plan of the baseor support, and

parent cylinder, the surface thereof bearing the imprint of figures, forprojection.

"In 'saidviews let 1 indicate a base or stand,

'whichis providedw'ith a central orifice 2 that is adapted to receivethe mount 3 for an'upwardlyext'ending electric light bulb 4;

l Ahollow', transparent cylinder 5 surrounds the-bulb land is providedwith atop 6, having a'seri'es of vanes 7 cut therein, said top alsohaving acentral bearing 8 iniits under surface. for support upon, therounded. end ofan'angled rodl'9 that is'h'ere shown'as engaged, at its"lower end; with the mount3.

It is intended that heat waves from the bulb 4., coacting with the vanes7, will serve V to rotate the cylinder 5.

The base 1 is providedin its upper surface 1 with an angular groove orrecess 10 which extends in somewhat the configuration of a star,

and a vertical shade 11, composed of trans lucent material, and whosecross-sectional contour corresponds with the contour of groove 10, isadapted to be seated in said groove, whereby said shade will surroundthe cylinder 5.

As has been premised the polygonal sides of the shade 1 1, hereindicated at 12, are of concavo-convex contour in crosssection, and attheir points of intersection, blunt or rounded connecting formations 13are provided.

It is by means of these particular contours 12, 13 in the polygonalshade that the figures 14 on the rotating cylinder 5, here representedfor example as fish, and projected by the light from the bulb upon theshade, appearto the observer as constantly varying in their shapes, andas rising and falling in their travel motion.

The cable connection to the lamp is indicated at 15, and may be providedwith a switch 16 located in a hole 17 provided thereforin the base.

Variations within the spirit and scope of my invention are equallycomprehended by the foregoing disclosure.

I claim: V

1. The combination with a lamp of a transparent, hollow cylindersurrounding said lamp, said cylinder being rotatably supported V il,878,750
